Brake fade
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
Excessive braking can cause all of the mentioned brake conditions. When brakes are applied forcefully for extended periods of time, it generates excessive heat, which can lead to warped brake rotors and drums. This heat also causes brake fade, where the brakes lose their effectiveness due to the overheating of brake pads and fluid.

Which of the following is MOST likely to be part of the hydraulic brake system?
- A.
Brake hoses
- B.
Wheel cylinder
- C.
Disc brake caliper
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
All of the options listed - brake hoses, wheel cylinder, and disc brake caliper - are commonly found components in a hydraulic brake system. Brake hoses are used to carry brake fluid between the master cylinder and the wheel cylinders or calipers. Wheel cylinders are responsible for applying the brake shoes to the brake drum, while disc brake calipers apply pressure to the brake pads against the brake disc to slow down or stop the vehicle. Therefore, it is most likely that all of these components would be part of a hydraulic brake system.Rate this question:

What should you never try to put out a gas, grease or flammable liquid fire with?
- A.
An ABC Fire Extinguisher
- B.
H2O
- C.
Baking Soda
- D.
Dirt
Correct Answer
B. H2OExplanation
Water should never be used to put out a gas, grease, or flammable liquid fire because water can spread the fire and cause it to become more dangerous. When water is applied to these types of fires, it can cause the flammable liquid to splash and spread, potentially causing the fire to grow larger and become more difficult to control. Additionally, water can react with certain chemicals and cause an explosion or release toxic fumes. Therefore, it is important to use the appropriate fire extinguisher, such as an ABC fire extinguisher, which is designed specifically for these types of fires.Rate this question:

The electrical system on the 1931 Model A out in the shop is a ______________ ground system.
- A.
Negative
- B.
Earth
- C.
Above
- D.
Positive
Correct Answer
D. PositiveExplanation
The electrical system on the 1931 Model A is a positive ground system. This means that the positive terminal of the battery is connected to the car's chassis, while the negative terminal is connected to the electrical components. This was a common setup in older vehicles, where the positive terminal was grounded to prevent corrosion and improve electrical performance.Rate this question:
-

Originally, the 1931 Model A came with a 6 volt ___________________.
- A.
Battery
- B.
Generator
- C.
Starter
- D.
All of the above.
Correct Answer
D. All of the above.Explanation
The correct answer is "All of the above" because the 1931 Model A originally came with a 6 volt battery, generator, and starter. These components were necessary for the proper functioning of the vehicle's electrical system. The battery provided the initial power to start the engine, the generator produced electricity to charge the battery and power the vehicle's electrical systems, and the starter was responsible for initiating the engine's combustion process. Therefore, all three options are correct.Rate this question:

The brakes on the Model A is a ___________________ brake system.
- A.
Hydraulically operated drum
- B.
Disc and Drum
- C.
Mechanically operated Drum
- D.
Snare drum
Correct Answer
C. Mechanically operated DrumExplanation
The correct answer is "Mechanically operated Drum." This means that the brakes on the Model A are operated by mechanical mechanisms rather than hydraulic or disc systems. In a mechanically operated drum brake system, when the brake pedal is pressed, a mechanical linkage activates the brake shoes, causing them to press against the drum and create friction, which slows down or stops the vehicle. This type of brake system was commonly used in older vehicles like the Model A.Rate this question:

Every 4 years regardless of mileage due to moisture contamination.
- D.
Never, water can't get inside the actuating system.
Correct Answer
D. Never, water can't get inside the actuating system.Explanation

A standard lead-acid car battery when fully charged should read ___________ volts when checked with the engine not running with a voltmeter connected to the positive and negative battery terminals.
- A.
12
- B.
12.2 to 12.4
- C.
12.6 to 12.7
- D.
12.9
Correct Answer
C. 12.6 to 12.7Explanation
When a standard lead-acid car battery is fully charged, it should read between 12.6 to 12.7 volts when checked with a voltmeter connected to the positive and negative battery terminals. This voltage range indicates that the battery is at its optimal charge level and is ready to provide power to the vehicle's electrical system.Rate this question:
-

The voltage regulator is bad causing high voltage.
- B.
The voltage indicates the alternator is most likely operating correctly.
- C.
There is voltage back feeding through the system causing the battery voltage to increase.
Correct Answer
B. The voltage indicates the alternator is most likely operating correctly.Explanation
A working charging system will put out close to 14 volts when the vehicle is running to maintain a charge in the battery and provide enough energy to run the lights and accessories.Rate this question:

If a group of lights on your car all go out at one time, and your fuse isn't blown, the most likely reason would be:
- A.
The lights are wired in a parallel circuit, so if one light burns out, they all go out.
- B.
The lights are wired in a series-parallel circuit, so if one light burns out, they all go out.
- C.
The lights are wired in a series circuit, so if one light burns out, they all go out.
- D.
The lights are wired in a closed circuit, so if one light burns out, they all go out.
Correct Answer
C. The lights are wired in a series circuit, so if one light burns out, they all go out.Explanation
The correct answer is that the lights are wired in a series circuit, so if one light burns out, they all go out. In a series circuit, the components are connected in a single path, so the current flows through each component one after the other. If one light burns out and breaks the circuit, the current cannot flow through the other lights, causing them all to go out.Rate this question:
-
- 29.
If one light in a group of lights on your car quits working, but no other lights in the same circuit are affected, the most reasonable explanation would be:
- A.
The lights are wired in a series circuit, so if one light burns out, the rest will remain illuminated.
- B.
The lights are wired in a parallel circuit, so if one light burns out, the rest will remain illuminated.
- C.
The lights are wired in an open circuit, so if one light burns out, the rest will remain illuminated.
- D.
The lights are wired in a main circuit, so if one light burns out, the rest will remain illuminated.
Correct Answer
B. The lights are wired in a parallel circuit, so if one light burns out, the rest will remain illuminated.Explanation
The most reasonable explanation for the given answer is that the lights are wired in a parallel circuit. In a parallel circuit, each light has its own separate path to the power source. Therefore, if one light burns out, the current can still flow through the other lights, allowing them to remain illuminated. This is different from a series circuit, where the lights are connected in a chain, and if one light burns out, the circuit is broken and the other lights will not work.Rate this question:
